Review comment:
Avoid pass an blank string to `processLine`, although in `processLine`
it will handle this
```
// we can not use "split" function directly as ";" may be quoted
val commands = splitSemiColon(line).asScala
var command: String = ""
for (oneCmd <- commands) {
if (StringUtils.endsWith(oneCmd, "\\")) {
command += StringUtils.chop(oneCmd) + ";"
} else {
command += oneCmd
if (!StringUtils.isBlank(command)) {
val ret = processCmd(command)
command = ""
lastRet = ret
val ignoreErrors = HiveConf.getBoolVar(conf,
HiveConf.ConfVars.CLIIGNOREERRORS)
if (ret != 0 && !ignoreErrors) {
CommandProcessorFactory.clean(conf.asInstanceOf[HiveConf])
return ret
}
}
}
}
```
